Getting it right the at the start- The Limits of Changing a Tax Case on Appeal
By Seelan Muthayan, Director
Introduction
In Baseline Civil Contractors (Pty) Ltd v The Commissioner for the South African Revenue Service (893/2024) [2026] ZASCA 20, the Supreme Court of Appeal (SCA) clarified the scope of Rule 32(3) of the Tax Court Rules. The Court confirmed that although a taxpayer may refine or expand its legal arguments on appeal, it may not introduce a new objection that attacks a different component of the assessment from that challenged at the objection stage.
The judgment sends a clear message to taxpayers and advisers alike: the notice of objection is critical, and errors or omissions at that stage may prove fatal later in the dispute process.
Factual Background
Baseline Civil Contractors (Pty) Ltd (“Baseline”) operates in the civil construction sector. For the 2018 year of assessment, Baseline reported gross income of approximately R320 million and claimed deductions totalling around R73 million under section 11(a) of the Income Tax Act 58 of 1962 (the ITA).
Included in these deductions was an amount of approximately R11 million, which Baseline contended constituted a distribution of profits paid to an alleged en commandite partnership, Baseline Group Limited Liability Partnership (BECP).
SARS disallowed the deduction, taking the view that the payment was not an expense incurred in the production of income, but rather a distribution of profits after income had already been earned. As such, it was not deductible under section 11(a), read with section 23(g) of the ITA.
Objection and Appeal
Baseline objected to the additional assessment on a narrow basis. Its objection accepted that the R11 million formed part of its gross income and challenged only SARS’s conclusion that the amount was not deductible. The objection was partially disallowed, prompting Baseline to appeal to the Tax Court.
At the appeal stage, however, Baseline adopted a materially different position. In its Rule 32 statement, it argued that the R11 million had never accrued to or been received by it at all, but had accrued directly to the partnership. On this basis, Baseline contended that the amount should never have been included in its gross income in the first place.
This argument shifted the focus of the dispute from deductibility to receipt or accrual, effectively challenging a different component of the assessment.
SARS objected to this new ground of appeal, arguing that it amounted to a fresh objection in contravention of Rule 32(3).
The Issue before the Court
The central question before the SCA was whether Rule 32(3) permits a taxpayer to raise a new ground of appeal that, in substance, attacks a different part or amount of the assessment from that objected to under Rule 7.
While Rule 32(3) allows new grounds of appeal to be raised, this is subject to an important limitation: the new ground may not constitute a new objection to a part or amount of the assessment that was not previously challenged.
The SCA’s Decision
The SCA dismissed Baseline’s appeal and upheld the decisions of the Tax Court and the Full Bench of the High Court.
The Court held that Baseline’s “receipt or accrual” argument was fundamentally inconsistent with its original objection. At objection stage, Baseline had accepted that the R11 million formed part of its gross income and disputed only its deductibility. By later asserting that the amount never accrued to it, Baseline was effectively challenging the inclusion of the amount in gross income, which is a separate and distinct element of the assessment.
The SCA emphasised that a taxpayer cannot simultaneously maintain that:
- an amount is part of its income but deductible; and
- the same amount was never its income at all.
Allowing such a shift would undermine the dispute‑resolution framework established under the Tax Administration Act 28 of 2011, which is designed to ensure that disputes are clearly identified and ventilated as early as possible.
The judgment reinforces several important principles of tax dispute procedure:
- The objection defines the battlefield
The notice of objection sets the outer limits of the dispute. An appeal is not an opportunity to advance an entirely new case. - New arguments are permitted, new objections are not
Rule 32(3) allows refinement or expansion of legal argument, but not a challenge to a different component of the assessment that was never objected to. - Consistency is essential
A complete change in the characterisation of an amount—such as moving from “deductible expense” to “not income at all”—is impermissible on appeal.
Practical considerations for Taxpayers and Tax Advisers
The decision carries important considerations:
- Draft objections comprehensively
Where there is uncertainty, objections should address all potentially relevant grounds, including receipt or accrual, deductibility, timing, and character. Failure to do so may permanently foreclose those arguments. Using a skilled adviser when proceeding with the dispute resolution is therefore crucial. - Adopt a clear dispute strategy from the outset
Procedural flexibility diminishes as a dispute progresses. Early strategic decisions can have lasting consequences. - Exercise caution in complex structures
In cases involving partnerships, profit‑sharing arrangements, or similar structures, the tax treatment of receipts and accruals should be carefully analysed before returns are submitted and objections lodged.
Conclusion
In closing, the Baseline Civil Contractors judgment is a clear warning that taxpayers cannot rewrite their tax case midway through the dispute process. While Rule 32(3) provides limited flexibility to refine legal arguments, it does not permit a taxpayer to introduce a new objection under the guise of an appeal.
For taxpayers and advisers alike, the lesson is unmistakable: the objection stage matters. Getting it wrong at the outset may leave no room to correct course later.
